No association of anti-osteoporosis drugs with COVID-19-related outcomes in women: a nationwide cohort study

This study was performed to evaluate whether the use of drugs in the treatment of osteoporosis in women is associated with COVID-19 outcomes. The results showed that the risk of hospitalization, intensive care unit admission, and mortality was not altered in individuals taking anti-osteoporosis drugs, suggesting no safety issues during a COVID-19 infection.

INTRODUCTION

Whether patients with COVID-19 receiving anti-osteoporosis drugs have lower risk of worse outcomes has not been reported yet. The aim of this study was to evaluate the association of anti-osteoporosis drug use with COVID-19 outcomes in women.

METHODS

Data obtained from a nationwide, multicenter, retrospective cohort of patients diagnosed with COVID-19 from March 11th to May 30th, 2020 was retrieved from the Turkish Ministry of Health Database. Women 50 years or older with confirmed COVID-19 who were receiving anti-osteoporosis drugs were compared with a 1:1 propensity score-matched COVID-19 positive women who were not receiving these drugs. The primary outcomes were hospitalization, ICU (intensive care unit) admission, and mortality.

RESULTS

A total of 1997 women on anti-osteoporosis drugs and 1997 control patients were analyzed. In the treatment group, 1787 (89.5%) women were receiving bisphosphonates, 197 (9.9%) denosumab, and 17 (0.9%) teriparatide for the last 12 months. Hospitalization and mortality rates were similar between the treatment and control groups. ICU admission rate was lower in the treatment group (23.0% vs 27.0%, p = 0.013). However, multivariate analysis showed that anti-osteoporosis drug use was not an independent associate of any outcome. Hospitalization, ICU admission, and mortality rates were similar among bisphosphonate, denosumab, or teriparatide users.

CONCLUSION

Results of this nationwide study showed that preexisting use of anti-osteoporosis drugs in women did not alter the COVID-19-related risk of hospitalization, ICU admission, and mortality. These results do not suggest discontinuation of these drugs during a COVID-19 infection.

Adult Eosinophilic Granuloma of the Lumbar Spine with Atypical Dissemination

Vertebral Eosinophilic Granuloma (EG) is a frequently reported disease, but further dissemination rarely occurs when the initial lesion is in the lumbar region. We present a case of EG, initially located in L5 vertebra, which disseminated to the skeletal bones and pulmonary system months after total excision in an adult.

Brucella diskitis mimicking herniation without spondylitis; MRI findings

A case of isolated brucella disk infection mimicking fragmented disk herniation is presented. MRI studies were performed two times in 6 months, both of which did not show any signs of spondylitis. Since brucella infections are seen along with spondylitis, this case has attracted our attention. We focused on radiological findings in this pure brucella disk infection.
